2 When the memb r 12 occupi 's'forwardposition and engages the upper end of'thespring to be 'compressed,the ends of the portions of member31'are located forwardlyof spacer 16 so that said upper or movable member 12 pcannotfbe accidentally retracted erm ved 9 .25 of members 11 and 12. The slots 26 formed in the flanges of member 12 are of proper length so as'to permit only the desired forward or rearward movement of member 12 with respect to member 11.

Jaw 19 is so disposed that the lower end thereof, including the ledges or flanges 24, is disposed a suitable distance below the bifurcated end of the lower member 11. When the tool is used as a valve lifter, the tool is placed in position so that the ledges 24 engage the next to the last coil of the spring 0 and the member 29 is swung in position so that its notched lower end 30 rests on flange F of the engine block. The rear end of the tool is now pressed downwardly so as to raise the forward or jaw end thereof, thereby movingthe spring upwardly from its seat so that the valve stem B can be disengaged from position. The disposition of portions 24 on ifl'erent horizontal planes with respect to each other provides for ready engagement of the jaw member 19 with the coil of the spring and the pivotal mounting of the jaw member on the ends 18 of the lever maintains the jaw in proper engagement with the spring during the pivotal movement of the lever.

To replace the spring, the tool after, the spring is compressed therebetween, is placed in inverted position as shown in Figure 9, wherein the jaw member 19 occupies upper position. This reverse position of the tool permits the location of the upper end of the spring in the upper end ofthe recess and at the same times provides suitable clearance between the tool and the upper flange of the opening E. When the spring is in position, the tool can be either retracted with both of the jaws disengaging the spring at the same time or the tool can be tilted so as to disengage the jaw 19 from the spring before the jaw 25 is disengaged- Thus it will be seen that the tool can be used for various purposes and that the use of the tool greatly facilitates the assembly and disassembly of the valve mechanism. a

The device is of simple but rugged con-v struction and contains very few parts which are not liable to get out of order. While I have shown and described the preferred form of my improved tool, it is ob-' vious that various modifications can be made in my invention without departing from the spirit thereof.
